Great short pistol barrel. Tack driver for such a short barrel. Three rounds in quarter sized group at 50 yds.
great factory Colt barrels.
The last barrel I purchased from you (SP402251) shot 1 in. groups at 100 yds. with a aimpoint T2 , I expect this one (SP401757) to do no less.
I’ve been watching for these barrels and AU got them in stock. The barrel arrived and it completed a M4 commando 6933 build I was wanting to put together. Barrel arrived new and in the Colt box. Next time out this build will be the first one to fire.
SHIPPING WAS DELAYED BUT THE BARRELS ARRIVED AS DESCRIBED NEW IN BOX IN METAL GUARD BAG. CANT COMPLAIN, AU DELIVERED!
Thanks again AU. Hard barrel to find, and awesome price with free shipping.
AU delivered the goods! Hard to find barrel at a very fair price! You would be very hard pressed to find a more accurate barrel in any length. Colt hardware is sometimes pricey, but you cannot deny the quality.Not always prettiest, but overall the best performance. After sighting in @50yds,then 100. This barrel is sub MOA with quality ammo...if you do your part. AU gtg all day!
Super fast shipping and the barrel arrived nicely packaged as expected! Love purchasing from AU as they always have exclusive items I’m looking for!
Been looking for a spare and AU had at the best price I have seen in a while. Well packed.
